Hazardous Substance Management
In compliance with IECQ QC 080000, the latest international regulatory trends, and customer requirements, the Company has established an ISO document titled “Green Product Specification Operating Procedure”. This document defines general requirements for prohibited and restricted hazardous substances in products (such as RoHS and REACH). Materials that meet regulatory requirements and are halogen-free are assigned specific part number identifiers and classified as “green raw materials”. This facilitates the selection of compliant materials by R&D teams during the product design stage, ensuring alignment with global regulations and the Company’s green product standards while reducing or gradually eliminating hazardous substances in products. All parts and packaging materials used in products must comply with international regulations and customer specifications regarding hazardous substances. The main controlled substances include the 10 RoHS-restricted substances, 247 REACH SVHCs, REACH Annex XVII substances, and other regulated substances under various regulations. In 2024, due to growing customer concern over per- and polyfluoroalkyl substances (PFAS), the Company initiated PFAS-related surveys and management across its supply chain in preparation for the anticipated global ban on PFAS by 2026.
There were no incidents of non-compliance with health and safety regulations related to products and services in 2024. In addition, green raw materials accounted for 96% of the Company’s total raw material procurement value.
Hazardous Substance Management Process
International Hazardous Substance Management Performance
| Key Regulatory Items | Compliance Status |
|---|---|
| Restriction of Hazardous Substances (RoHS) in various countries | Compliant |
| Halogen-free requirements | Compliant |
| EU Registration, Evaluation, Authorization, and Restriction of Chemicals (EU REACH) | Compliant |
| Material Declaration Standard for the Electrotechnical Industry (IEC 62474) | Compliant |
| Montreal Protocol | Compliant |
| U.S. Toxic Substances Control Act (TSCA) | Compliant |
| Persistent Organic Pollutants (POPs) regulation | Compliant |
| Per/Poly fluoro alkyl substances (PFAS) | Suppliers are required to declare: “If materials contain PFAS, the R&D team will conduct alternative material screening and replacement.” |
In 2015, the Company independently developed and implemented the “Green Product Management System (GPMS)”, which incorporates a built-in Hazardous Substance-Free (HSF) management system. Green material management is carried out by the “Green Product Management Operating Procedures”, while suppliers and contractors are required to comply with the “Green Procurement Specifications” and provide a “Green Product Warranty”. The system is integrated with the material and component approval process for effective control. Procurement contracts stipulate that materials, parts, or semi-finished products provided by suppliers must comply with hazardous substance control requirements for green products. Through sustainable supply chain management, the Company aims to promote the use of environmentally friendly materials and to manufacture and supply customers with low-toxicity and low-pollution products, thereby reducing harm to human health and the environment and preventing non-compliant materials, parts, or products from entering the Company and potentially causing ecological damage due to misuse. In addition, strengthening control over conflict minerals and ensuring that the materials purchased by suppliers better comply with RBA requirements, the Company established a “Conflict Minerals System” at the end of 2024, which is scheduled to launch officially in 2025.
